Inf-Hesitant Fuzzy Ideals in BCK/BCI-Algebras

Young Bae Jun, Seok-Zun Song (2020)

Bulletin of the Section of Logic

Similarity:

Based on the hesitant fuzzy set theory which is introduced by Torra in the paper [12], the notions of Inf-hesitant fuzzy subalgebras, Inf-hesitant fuzzy ideals and Inf-hesitant fuzzy p-ideals in BCK/BCI-algebras are introduced, and their relations and properties are investigated. Characterizations of an Inf-hesitant fuzzy subalgebras, an Inf-hesitant fuzzy ideals and an Inf-hesitant fuzzy p-ideal are considered. Using the notion of BCK-parts, an Inf-hesitant fuzzy ideal is constructed....

On the transfer principle in fuzzy theory.

Similarity:

We show in this paper that almost all results proved in many papers about fuzzy algebras can be proved uniformly and immediately by using so-called Transfer Principle.
